Fresh Jessie installation about a week ago, Trinity added tonight. Using startx rather than any DM. Mouse can be used to select and click, but no way to tell where pointer is until it hovers something that changes on hover. Same problem in IceWM. Booting openSUSE Leap instead, pointer works normally in IceWM. Both evdev and mouse input drivers are installed. Google can't find anything helpful except WRT *buntu, rsyslog, arm or raspberry pi. Anyone here had this happen and/or know a fix?
